Title: Image display device using magnetism type image display element
Inventor: NOMURA MASAAKI
IPC: G02F1/19
Filed: 1979-07-03
Abstract: PURPOSE: To obtain an image display device which is small in size, does not consume any electric power and is easy to use by so constituting the device that the magnetic pieces disposed in the respective concave parts of an image display plate are inverted according to the magnetisms of the magnetic fields applied whereby images are displayed.  
     CONSTITUTION: Magnetic pieces 5 of which the front face 5a is of an N pole and is black and the back face 5b is formed to white or an arbitrary color are put together with transmittable liquid such as e.g. water into the respective concave parts 4a of a case 4 composed of a nonmagnetic material. The N pole of a permanent magnet 9 is brought closer to the lower side of this image display element 8 to let the front faces 5a of the magnetic pieces 5 face upward so that the entire part of the top surface appears black. Next, when the S pole of the magnet 9 is brought closer to the lower side of arbitrary concave parts 4a of the display element 8, the back faces 5b of the magnetic pieces 5 face upward and only that portion appears white or in other color. Hence, if a magnetic field is applied to the desired image shape from the lower side of the respective concave parts 4a of the image display element 8, the image of white or a desired color may be displayed on the black ground. In this way, the easy-to-use image display device is obtained.
